IMPROVEM ENT IN ODOMETERS.

Specilication forming part of Letters Patent No. 221,652, dated November 11, 1879; application tiled April 1, 1879.

To all whom it may concernl Be it known that I, ANDREW YoUNT, of Kokomo, Howazd coni'ity, Indiana, have invented an Improvementiu Odometers, of which the following is aspecification.

My invention relates to instruments used for measuring the distance traveled by vehicles; and it consistsin an improved const-ruction of a registering apparatus, and also in an improved construction of devices for transmitting motion from the wheel of the vehicle to the said registering apparatus.

The particular features which constitute my invention are described in connection with other parts necessary to show the operation, and are specitically indicated in the claims.

In the drawings hereunto attached and forming part of this speciiica-tion, Figure 1 represents a side elevation of the apparatus as applied to the axle of thewheel. Fig. 2 is a view otl the upper part of the same. Fig. 3 is a view of the side opposite that shown in Fig. 1. Fig. 4 is a view of the face ot' the dials with the plate removed. Fig. 5 is a transverse central section ot' the same; and Fig. 6 is a vertical longitudinal central section ot' the axle and part ofthe hub, showing the connection ot' the devices for transmitting motion from the wheel.

This device (marked D in the drawings) consists of a rin g bent, as shown more clearly in Fic. 2, to form a double cam upon the sides thereof. It is pivoted at the angles, as shown at r and s, by pins or screws, which pass into the axle and hold the ring securely in place, permitting the required oscillation. Upon the end oi' the hub, within the shell (l, is a pin, K, which projects, as shown more clearlyin Fig. 2, nearly to the pivoted part of the ring D, and is so arranged in relation to the said ring that the revolution of the wheel in either direction causes the pin K to move along the inclined face of the ring D and push one side of it back away from the inner end of the hub. The other side of the ring, being thrown in the opposite direction, may move under and within the shell C, and the further rotation of the wheel, or one complete revolution, will throw that side in its turn backward away from the inner face of the hub. Thus the rotary motion of the hub imparts an oscillating movement to the camshaped ring. This motion is transmitted to the recording apparatus by means of the connecting-rod I, attached on one side ofthe axle to a point on the ring D inidway between the two pivots of t-he said ring. This rod I is pivoted at the other end, at n, to a crank, H, upon the end ofa shaft, c2, which passes centrally through the tirst wheel ot' the recording apparatus.

The first wheel of this recording apparatus revolves upon the shai't thus described; and tixed to this shaft, on the face side ot' the recording ai'iparatus, is an arm, a', which carries a spring-pawl, t having its end bent inwardly toward the wheel.

Notches upon this wheel, which is marked c, are arranged in the edge at distances corresponding to the stroke imparted to the rod I bythe motion of the ring D, so that the inwardly-bent end of the pawl y travels at each stroke from one notch to the next, the wheel being held while the operating-pawl is moving backward by the stationary springpawl L. A disk, d, on the wheel e bears against the face of each section of the next wheel, hollowed between the notches to tit it. This disk e' is cut away upon one side, and opposite the side so cut away is a small pin, t, set in the iacc ot' the wheel, and at such a point that as the wheel e revolves the pin t shall enter one of the slots or notches in the face of the next wheel. As the space between the said notches or slots in the next wheel is hollowed to"'t`1t the edge ot' the disk e, it is obvious thatthe succeeding wheel cannot move until in the revolution of the preceding wheel the notch opposite the pin t is brought. round to face the said contiguous wheel. The pin, then entering the notch, moves the wheel nextin order, and the points next the notches are tree to move in the space left by the nick in the disk o. Thus the complete revolution of the first wheel moves the second wheel one notch.

The construction ot' lthe succeeding wheels is precisely the same as the second wheel, as will appear plainly from Fic. 4 ot' the drawings, and the operation is the same.

The pin q upon the wheel d, opposite the notch in the disk d', moves in the slot or notch in the wheel c, the disk el holding the wheel last named until the pin q opposite the nicked side ot' d comes around to its place in the notch.

The figures upon the first wheel represent units, the second tens, the third hundreds, and so on, so that one hundred thousand revolutions ol" the wheel ot' the carriage mayv be registered. Any number of these registeringwheels may be used, according to the requirements ofthe case. These wheels are set in a metallic plate, M, cast in the forni shown in Figs. 4 and 5, and litted to receive the wheels. Over this is placed a metallic plate, F, Figs. l and 2, into which and under the slot at the end is slid a cover, and underneath the cover a glass plate, the cover being-clearlyY shown in Ifig. l. The openings in the plate E allowthe ligures to be read, which show the number of revolutions ofthe wheel 1n any given time.

Manifestlytheregistering-wheelsmaybe covered by any convenient form ot' ease which will allow easy inspection, and will permit the register-ing-wheels to 'ne secured against unauthorized intrusion and tampering with by unauthorized parties.

'lhe use of wheelshaving gures on the l'aee,

which may he arranged, as shown, from one to ten, permits a simplilication of the parts and dispenses with under figures. The succession ot' small wheels can be placed convenientlyr along the side of an ordinary axle, where larger wheels would he exposed. rIhe ring and operating devices are located in a protected position, and out ot' the way ofthe mud and dust.

Having thus described my invention, what I claim` and desire to secure by Letters Patent ot the United States, is

l. Acombinatonot'theringl),thepinK,and the rod I, communicating motion to the registering-wheels, as and for the purpose set l'orth.

2. The combination ot' the rod I, the crank II upon the pivot or shalt e', the arm m, the spring-pawl y, and the wheel c, as and t'or the purpose set forth.

In testimony whereofl havesigned my name to this specilieation in the presence of' two suhserihing witnesses.

ANDREW YOUN'I.
